Electroplated Diamond Wire Saw

Electroplated Diamond Wire Saw for Precision Cutting — Superior Sharpness & Extended Service Life

Laizhou Jinfuen Machinery Co., Ltd. offers high-performance electroplated diamond wire saw tailored for precision slicing of silicon wafers, sapphire, SiC, GaN and graphite materials. Adopting independent proprietary surface coating technology, our product bonds synthetic diamond micro-powders firmly and evenly onto ultra-thin alloy steel cores (minimum diameter up to 0.1mm) via nickel-based electroplating process. This fixed-abrasive cutting mode abandons traditional slurry-dependent cutting, effectively reducing kerf loss and boosting material yield by replacing loose abrasive rolling with precise micro-grinding. We support a minimum order quantity of 1 piece, with a delivery cycle of 10–30 days.

What Is an Electroplated Diamond Wire Saw?

Different from conventional slurry cutting systems, this advanced technology fixes diamond particles stably on the wire surface. It completely converts the cutting principle from loose abrasive rolling to

As a result, it delivers higher cutting efficiency, lower kerf loss, reduced wire breakage rate and better workpiece surface finish, which are core performance indicators for industrial B2B manufacturing production.

Key Product Characteristics

Ultra-thin core diameter: We adopt premium special alloy steel cores with a minimum diameter of 0.1mm, which greatly minimizes kerf loss and maximizes material utilization rate in every cutting process.

Proprietary bonding technology: The exclusive surface coating process ensures uniform distribution and firm bonding of diamond grains in the nickel matrix, effectively avoiding premature diamond shedding even under high-speed and high-pressure cutting conditions.

Exceptional tensile strength: The core wire features a tensile strength of 3200 to 4500 MPa, owning stable mechanical properties to adapt to high-speed reciprocating and unidirectional tension working conditions in continuous slicing operations.

Precision diamond grit calibration: The diamond grit size is precisely calibrated within 5–30μm, which can balance material removal rate (MRR) and surface roughness (Ra) according to customers’ actual application scenarios.

Superior thermal conductivity: The unique electroplated structure realizes efficient heat dissipation during cutting, effectively reducing thermal damage to brittle substrates such as silicon wafers and sapphire.

Technical Specifications

Applications

Electroplated diamond wire saw covers multiple high-precision industrial cutting scenarios, fully meeting the stringent processing requirements of various hard and brittle materials.

Photovoltaic (PV) wafering: It is widely used for slicing monocrystalline and polycrystalline silicon ingots. The ultra-low kerf loss effectively reduces unit material consumption, directly lowering the per-watt production cost for large-scale PV manufacturing.

Semiconductor substrate dicing: Ideal for processing ultra-hard wide bandgap materials including Silicon Carbide (SiC) and Gallium Nitride (GaN). With high diamond protrusion and ultra-strong bonding force, it is the most reliable cutting solution for high-hardness semiconductor substrates.

Precision optical and sapphire cutting: Suitable for LED substrate production and high-end watch crystal processing. It ensures high dimensional accuracy and low Total Thickness Variation (TTV) even in complex high-pressure cutting environments.

Graphite block and slab cutting: The flexible closed-loop cutting structure adapts to the brittle and abrasive characteristics of graphite, delivering smooth and burr-free cutting surfaces while maintaining stable cutting efficiency.

Quality Control Process

Every roll of our electroplated diamond wire saw undergoes strict multi-stage testing and inspection before delivery to ensure stable and consistent product quality.

Diameter consistency inspection: Laser micrometers are used for full-length continuous monitoring to control the overall tolerance within ±1μm, with all unqualified products eliminated immediately.

Mechanical performance test: A universal testing machine is adopted to detect the breaking load and elongation rate of the wire saw, ensuring it can withstand continuous tension in formal production.

SEM diamond morphology analysis: Verify the uniform distribution and reasonable embedding depth of diamond particles to prevent particle shedding during cutting.

Torsion and bending test: Check the structural stability of the electroplated nickel layer to ensure no cracking or delamination under high-speed cutting mechanical stress.

Surface cleanliness detection: Remove residual oil stains and metal ions on the wire surface, meeting semiconductor-grade cleanliness standards and protecting customer workpieces from contamination.

B2B Purchasing Value

Purchasing directly from our factory helps customers completely save intermediate agency costs. We support customized configurations of wire diameter, diamond grit size and spool length, providing targeted cutting solutions instead of generic standard products.

With more than 30 years of professional manufacturing experience, our team provides one-stop technical support including product selection guidance, cutting parameter optimization and after-sales spare parts service for all orders.

All products are stored in vacuum-sealed and low-humidity environments, with a valid service life of 6–12 months. We adopt industrial-grade anti-corrosion export packaging to ensure intact product delivery worldwide.

Frequently Asked Questions

Q1: What are the main causes of wire breakage during high-speed slicing?

A1: Wire breakage is mainly caused by uneven equipment tension, excessive linear speed (over 1500 m/min) without sufficient cooling, or micro-cracks on the steel core. Calibrating equipment parameters and optimizing coolant conditions can effectively avoid this problem.

Q2: How does diamond grit size affect cutting performance?

A2: Fine grit delivers better surface roughness and lower TTV but reduces cutting efficiency; coarse grit improves material removal rate yet may cause slight subsurface damage. We can recommend the most suitable grit size based on your processing needs.

Q3: Why is electroplated wire more suitable for SiC cutting than resin-bonded wire?

A3: Electroplated wire features higher diamond concentration and stronger bonding strength, which can withstand the high-pressure grinding required for ultra-hard SiC materials. Resin-bonded wire cannot maintain stable performance under such harsh cutting conditions.

Q4: How to optimize coolant for the wire saw?

A4: It is recommended to use high-lubricity synthetic coolant and maintain a stable pH value to prevent corrosion of the nickel electroplated layer, which can effectively extend the service life of the wire saw.

Q5: What is the shelf life of your electroplated diamond wire?

A5: Under vacuum-sealed and low-humidity storage conditions, the product can maintain complete performance stability for 6–12 months. Moisture exposure will lead to core oxidation and coating degradation.

Q6: Do you support customized product specifications?

A6: Yes. We support full customization of wire diameter, diamond grit size, spool length and core material. The MOQ is only 1 piece, suitable for both sample testing and mass production.
